CKS1BP7 is amplificated in 28.8% of all patients, amplified IGF1R in 24.2%amplification of them often co-existed togetheridentical CNAs of CKS1BP7 and IGF1R were found in DCIS and invasive carcinoma within the same tumorsamplification of both genes was more frequent in aneuploidy tumors and the tumors with high ki67no association of amplification and patient outcome. The gene discussed is IGF1R; the disease is ductal breast carcinoma in situ.
